DIFFUSION APPARATUS.

SPECIFICATION forming' part of Letters Patent No. 471,995, dated March 29, 1892.

Application filed February 16, 1891. Serial No. 381,618. (No model.)

To aZZ whom t may concern:

Be it known that I, EDWARD GscHwIND, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in a-Diffusion Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichitappertains to make and use the same.

My invention relates to an improvement in a diffusion apparatus; and its novelty will be fully understood from the following description and claims, when taken in connection with the annexed drawings. The objects of my invention are to enable saccharine matter to be removed from the crushed cane or bagasse by saturating same with water and transferring the bagasse from one tank to another of a series of tanks. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a side view. Fig. 2 is a longitudinal section. Fig. 3 is a top plan view. Fig. 4 is a top view of a portion of the apparatus. Fig. 5 is a side view of gearing. Fig. 6 is a section through the buckets.

Similar letters and figures refer to similar parts throughout the several Views.

In the drawings, A refers to a chute through which the cane passes to the three-roller mill B, which rests on a base C. D are j nice-tanks. E are knives mounted by suitable means and which cut the crushed cane or bagasse after it passes from the three-roller mill and descends through chute F. The material thus out falls into one of a series of transverse tanks. (Shown in Figs. l and 2 and designated G.) These tanks are preferably of a semicircular form in cross-section, whereby the material to be saturated can be removed from one to the other, as will be presently described, until it reaches the elevator-well H, where it is conveyed by elevator L to chute M and passes through two-roller mill N, the juice descending into tank D and the bagasse passing out through chute O, and can be utilized as fuel or paper-stock.

Journaled in the end Walls of each tank G is a rotatable shaft 13, which carries three equidistant radial blades 22, which extendv longitudinally of the tank and are provided adjacent their outer edge with an angular branch b,whereby angular buckets are formed on eachblade fora purpose presentlydiselosed.

Fixed on the ends of the shafts 13 of the several tanks are beveled gears 12, with which mesh beveled pinions Il, fixed on a longitudinal shaft 14, whereby it will be perceived that the shafts of the several tanks are rotated at a corresponding' speed and in a uniform direction. The longitudinal shaft 14 is provided at one end with a beveled gear l0, with which meshes a beveled bear 9 on one end of atransverse shaft c, which also carries a pulley 7, which is connected to and driven by a pulley 6 on a power-shaft d through the medium of a belt S.

Fixed on the power-shaft d is a pulley 5, which is connected by the belt 4 with a suitable motor, and fixed on the end of said shaft d is a pinion e, which meshes with a gear f on the end of the shaft of the lower roller N, which meshes with a gear-Wheel gon the shaft of the upper roller N. A sprocket-wheel 15 is also fixed upon the end of the shaft of the lower roller N and is connected by a chain belt 17 with a sprocket-wheel 16 on the upper elevator-shaft.

Journaled between the tanks G are transverse shafts 25, on which are xed radial guards or discharging-plates 2l, which extend longitudinally of the tanks and upon which the bagasse is discharged from the buckets of the blades 22, and when in their normal position said plates are pitched on an incline toward the tank from which they receive bagasse. The movement of the plates 2l is limited by lateral studs 26, arranged at a suitable point atvthe sides of the pivotal points thereof.

P indicates longitudinal sliding shafts, which are pivotally connected at their forward ends by means of crank-levers to the ends of shafts 25, While the opposite ends of said shafts are provided with a depending angular branch adapted to be engaged by three lateral studs 23, extending inwardly at equidistant intervals from the gear-wheel l2. The studs 23 are placed upon the gear-wheel 12, with respect to the blades 22 upon the roo shaft 13, s0 that when each blade 22 is in a position to discharge one of the studs 23 of gear-wheel 12 will engage the angular branch of the slide-shaft P, whereby it will be seen that the plate 21 will be swung in the direction of the next tank and the bagasse on said plate will be thrown into said tank.

As better illustrated in Fig. 2 of the drawings, the several sets of cup-carrying blades of the several tanks G are so arranged on their respective shafts with respect to each other that when a blade of one tank is in a position to discharge, the blades of the next succeeding tank will be in such a position that the bagasse will be immersed in the water of said tank before it is raised and discharged into the next tank.

K indicates a furnace beneath the tanks G, whereby the water therein may be kept in a heated state, as is desirable.

2O indicates-the smoke-pipe of the furnace.

19 indicates cocks leading from the tanks G, whereby the juice or liquid may be drawn therefrom.

18 indicates a feed-water pipe, which is connected with the several tanks by branch pipes, and 19 indicates waste-cocks leading from the tanks.

In operation the bagasse as it falls from the knives E is carried into the first tank G, and from thence is discharged into the next tank, and so on through all the tanks until it is discharged into the elevator-well II, from whence it is elevated and carried through squeezing or crushing rolls and finally dis charged.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a diffusion apparatus, the combination, with a series of tanks arranged adjacent to each other, of a rotatable shaft journaled in each tank, the blades fixed on said shaft and carrying cups, the rock-shafts journaled between the respective tanks and carrying radial plates, and a suitable means for actuating the rotatable shafts and rock-shafts, substantially as specified.

2. The combination, with a series of tanks, the rotatable shafts jonrnaled, respectively, in each tank, radial blades fixed on the said rotatable shafts and carrying cups, and gearwheels fixed on the ends of the rotatable shafts and carrying inwardly-directed lateral studs, of plates fixed on shafts journaled between the respective tanks and longitudinal slide -shafts connected by levers with the shafts of said plates and adapted to be engaged by the studs of the gear-wheels, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
